Claims (1)
- 蛍光膜付きのアノードと、このアノードに対向配置された電界放射型のカソードと、アノードとカソードとの間に介装されたグリッドと、を備えた電界放出型光源において、
上記アノード、カソード、グリッドそれぞれの全領域を複数のアノード領域、カソード領域、グリッド領域に分割するとともに各グリッド領域に半導電性薄膜をチャージアップ部材として設け、
上記カソードは、複数のグリッド領域にまたがる長さの導線と、該導線の表面に多数の微細突部を有する炭素薄膜を設けて構成されており、
各グリッド領域のチャージアップ部材は対応するカソード領域からの電子放出量に対して相対的にチャージアップしてグリッド領域からの電子通過量を制御して、各グリッド領域からそれに対応する各アノード領域への電子密度をほぼ同等化して蛍光膜がその全体から均一化した発光輝度で発光することを可能とした、ことを特徴とする電界放出型光源。
